DART AP-PD Asphalt Release Spray System

Model # 977800

The DART AP-PD Asphalt Release Spray System is a push button activated asphalt release sprayer for coating any length asphalt truck bed with pre-diluted asphalt release agent. When the system is activated, a delay timer allows the driver to position the truck under the spray nozzle before applying release agent. The run timer controls the amount of spraying time, after which the system shuts down and resets.
